Abstract
It the utility model is related to a kind of cold drawing steel tube in concave section.It includes tube body, the tube body is in " mouth " shape, four corner outwardly convexs of tube body, which are formed, strengthens side, the reinforcement side includes the first straight flange, second straight flange and bevel edge, the first straight flange and the straight flange of the second straight flange and tube body are uniformly provided with the first mounting hole by arc transition on one side of the tube body, the second mounting hole, the first mounting hole and the second mounting hole the dislocation arrangement are uniformly provided with another opposite side of tube body.A kind of cold drawing steel tube in concave section of the utility model, stability is good, be unlikely to deform bending and it is easy for installation.
Description
Technical field
It the utility model is related to a kind of seamless steel pipe, more particularly to a kind of solid drawn tube.
Background technology
The whole non-jointed steel pipe of steel tube surface that cold drawing steel tube is produced with the methods of drawing, extruding, perforation.It is a kind of
With hollow section, the non-jointed circle in periphery, square, rectangle steel.It is that hair is made with steel ingot or solid pipe billet perforated
Pipe, is then made through cold group.
Cold drawing steel tube be for mechanical structure, the dimensional accuracy of hydraulic test is high and surface smoothness is good accurate cold-drawn without
Slit-tube.However, traditional solid drawn tube is substantially round tubular structure, it is impossible to effectively antitorque, it is impossible to meet each side
Use demand；The solid drawn tube stability of existing single shape is poor, and when being arranged with cross modal, assembling process
Easily collide between middle workpiece and workpiece, can not meet the demand of client.
The content of the invention
A kind of the purpose of this utility model is to overcome above-mentioned deficiency, there is provided cold drawing steel tube in concave section.
What the purpose of this utility model was realized in：
A kind of cold drawing steel tube in concave section, its main feature is that：The cold drawing steel tube in the concave section includes tube body, the pipe
Body is in " mouth " shape, and four corner outwardly convexs of tube body, which are formed, strengthens side, and the reinforcement side includes the first straight flange, the second straight flange with
Bevel edge, the first straight flange and the straight flange of the second straight flange and tube body are uniformly provided with one side of the tube body by arc transition
First mounting hole, is uniformly provided with the second mounting hole, first mounting hole and the second peace on another opposite side of tube body
Fill hole dislocation arrangement.
Compared with prior art, the beneficial effects of the utility model are：
1st, a kind of cold drawing steel tube in concave section of the utility model, four corners of tube body form the reinforcement of outwardly convex
Side so that the overall stability of tube body is good, is unlikely to deform bending.
2nd, a kind of cold drawing steel tube in concave section of the utility model, the both sides of tube body have the first mounting hole and second
Mounting hole, two mounting hole mutual dislocations so that cold drawing steel tube will not be touched when intersecting installation between workpiece and workpiece
Hit, ensure that being smoothed out for installation.
Brief description of the drawings
Fig. 1 is a kind of sectional view of the cold drawing steel tube in concave section of the utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
In figure：
Tube body 1,
Strengthen side 1.1,
First straight flange 1.1.1,
Second straight flange 1.1.2,
Bevel edge 1.1.3,
First mounting hole 2,
Second mounting hole 3.
Embodiment
Referring to Fig. 1-3, a kind of cold drawing steel tube in concave section is the utility model is related to, it includes tube body 1, the tube body 1
In " mouth " shape, four corner outwardly convexs of tube body 1, which are formed, strengthens side 1.1, and the reinforcement side 1.1 includes the first straight flange 1.1.1,
Second straight flange 1.1.2 and bevel edge 1.1.3, the first straight flange 1.1.1 and the second straight flange 1.1.2 and the straight flange of tube body 1 pass through circular arc mistake
Cross, the first mounting hole 2 is uniformly provided with a side of the tube body 1, be uniformly provided with another opposite side of tube body 1
Second mounting hole 3,2 and second mounting hole 3 of the first mounting hole are staggeredly arranged.
Operation principle：Four corners of tube body 1 form the reinforcement side of outwardly convex so that and the overall stability of tube body 1 is good,
It is unlikely to deform bending；The both sides of tube body 1 have the first mounting hole and the second mounting hole, and two mounting hole mutual dislocations, make
Cold drawing steel tube is obtained when intersecting installation, will not collide between workpiece and workpiece, ensure that being smoothed out for installation.
